Thyme Roasted Mushrooms with Millet Polenta

Thyme Roasted Mushrooms with Millet Polenta

This simple yet delicious meal recipe was shared in my first newsletter, sent out last Friday. Since is almost time for the next newsletter, I share it here for easy reference. This thyme roasted mushrooms with millet polenta meal were inspired by the October issue of Bon Appétit magazine. They always have great ideas for seasonal meals and I love making some of them Plant Paradox compliant.

Thyme roasted mushrooms with millet polenta, a lectin-free dinner that feels like home

I love mushrooms and polenta but for obvious ‘lectin-free reasons’ corn flour polenta is not an option in our home. Fun fact: I grew up eating polenta, which is a traditional daily dish in Romania, served as an accompaniment for the everyday Romanian stew. Mushrooms and thyme are also staples in Romanian cuisine, so this meal felt pretty familiar. I enjoyed roasting the mushrooms, make sure you get the edges crispy by broiling them at the end, it makes for an amazing umami flavor.

Millet can be tricky. It has to be good quality but I’m not sure yet what makes a good quality millet. At first, when I tried millet I would always have grains in the batch that would stay crunchy. I even heard someone saying that the whole batch of millet didn’t soften after 20 minutes of boiling in x4 times the liquid. My last experience was perfect. I bought it from the bulk section at Whole Foods and it worked nicely for this dish.

As per millet flour, sometimes used to make polenta, I tried it and it was a failure. I don’t like the texture, and it tastes bitter, so I totally recommend using the grains.

Prep Time: 15 minutes Cooking Time: 35 minutes

An easy and warming lectin-free dinner idea.


  • 1.5 lbs mixed mushrooms (I used oyster and mini portobello, but you can use a more diverse mix)
  • few springs of fresh thyme plus more for serving
  • 6 garlic cloves, unpeeled and slightly smashed
  • Himalayan pink salt
  • pepper
  • extra virgin olive oil
  • 1/2 cup millet (grains, not flour)
  • 2 cups water
  • 1/2 tsp iodized sea salt
  • 1 or 2 tsp French butter
  • a small handful of grated Pecorino Romano



TO MAKE THE ROASTED MUSHROOMS: Wash and pat dry the mushrooms and cut them into medium chunks. Add them to a large baking sheet, add salt, pepper, thyme, garlic and extra virgin olive oil, toss and mix. Bake, on the upper rack, at 350F for about 25 minutes, and broil for another 5-7 minutes at 400F. While the mushrooms are in the oven, you will make the polenta.


TO MAKE THE MILLET POLENTA: Heat a stainless steel saucepan (about 3QT) on medium heat and add the dry millet. Slightly roast the millet in the dry pan until it becomes fragrant (make sure you stir continuously so it doesn't burn). When you start to smell the millet being roasted add the water (being careful with the hot pan, a lot of steam will be released). If you see impurities coming to the surface, check the water level, throw that water away and replace it with a new one. The reason I don't wash it first is that I like to roast the grains first when they are dry. And I don't always throw the water but if I see too many Impurities in the water I do it. Add the salt and cook on low to medium heat until all the water is absorbed, it will take about 20-25 minutes (stir regularly). Transfer to an oven-resistant dish, add the butter and half of the cheese and mix. Add the rest of the cheese on top and broil at 425F for about 5 minutes.

    Hello, the aromas from this recipe were divine! Unfortunately, the mushrooms were so wet in the oven. I’ve been broiling them now for 20 minutes so the water evaporates. Can’t wait until they get crispy. I used a combination of baby bellas, shitaki, and oysters. I wonder if the oysters are too water-laden? In the end, they turned out wonderfully! Did the mention the scent that filled the home? Thank you 🙂

      Hi Tammy, yes you are right, the roasted mushrooms with thyme smell divine. I think out of all the mushrooms types you use, oysters give a special flavor and texture to this dish, so I would keep them. Bellas are possibly more watery, did you dry them well before cooking? But it’s ok anyway, depending on the types you use you can adjust the cooking time and temperature, or as you did, keep them more under the broiler. Thank you for letting me know, I’m happy you enjoyed this dish. xx

    Oh, I forgot to mention… I used waterless cookware to cook the millet. I toasted it, pured the 2 cups of water in carefully, covered, turned the heat down to low, and the water absorbed just fine into the millet. Maybe a bit of pressure cooking helped it?

    I’m so sorry….I clicked on the stars to be able to read about the review and it thought I was rating it with 4 stars. Mistake on my part. I have not made this, so wish I could make it go back to 5. I’m sure it’s delish.

    This recipe has a lot of flavor and it’s one I will make again, but didn’t have great success with the millet. I’ve only cooked millet one other time. I definitely needed to cook longer. It wasn’t right. Will try again. Would it help if I covered the pot while it cooked?

    Thank you for wonderful recipes Claudia. You are an inspiration!

      Hi Lori, thanks for getting in touch. This method should work well for cooking millet on the stove. Maybe the heat was too high? If you feel the millet is not cooked, you can always add more liquid and continue to cook until is done. Especially when you make polenta since you need a porridge texture. It’s more difficult when you want grainy millet, for salads or couscous. For that, the best method is pressure cooking. 1 cup millet, 1 cup water, start by toasting, add water and pressure cook for 10 minutes. Natural release. Fluff with a fork. That being said, sometimes I had millet that wasn’t cooked equally, some grains would stay hard. It might be the type of millet too. Anyway, do it more times until you get familiar, like with anything is a question of practice. xx

    So, in general, should millet be washed (or rinsed) before it’s cooked??

      It’s not necessary. If I only boil it, I will wash it. If I want to toast it first for extra flavor, I won’t. Depends also on the brand and where you get it from.

    Love it! Super easy to make, the polenta tastes amazing and it’s a great replacement for the corn polenta this Romanian is used to. Thanks a lot for the recipe!
